Car Will Not Go Into Diagnostic Mode

When I jumper the pins to put it into diagnostic mode nothing happens.

Anyone have an idea what this could be, is there a fuse that powers it.

BTW the car is a 1992 Camaro RS that I swapped an LB9 into, its speed density TPI

Any help would be appreciated.

Thanks!

When this happened to me, I changed out the computer and the car ran perfect. Hope this helps.

I changed it out yesterday and had no success unfortunately, thanks for trying to help though. Next step is to drop it off at an electrician because I am defeated.
